Typically, customers who want to deliver data at 2-Mbps rates between their remotely located equipment have had to rely upon lease-line services provided by a PTT or Telco. Using the Model 1186, however, customers can extend the G.703 signals on their high speed multiplexers or cellular base stations using Multimode fibre. The NetLink Model 1186 Multimode fibre modem is a low-cost alternative to leasing G.703 services when connecting remote locations. A pair of NetLink 1186s deliver 2.048 Mbps clear channel data across a single strand of Multimode fibre at distances up to up to 2.5 km (1.6 miles), which makes the Model 1186 ideal for limited-distance applications (see diagram below). The 1186 provides 120-ohm (RJ-48) and 75-ohm (dual-coax) options for connecting the G.703 interface of a CSU/DSU, multiplexor, or base station. The modem sends AMI- or HDB3-encoded data over Multimode fibre to the remote NetLink 1186.
ST or SMA fibre interfaces are available. The Model 1186 are also available as a rack card for use in a NetLink 1001 2U rack chassis. The NetLink 1001 rack system provides dual-redundant AC and/or DC power options and includes all the features of the standalone units.If you need Singlemode capability, check out the Model 1193 modem. A pair of Model 1193s deliver 2.048 Mbps clear channel data across a single strand of Singlemode fibre at distances up to up to 50 km (31 miles)! That’s five times further than distances available over xDSL!
